David Pilato 8d35bca4db Add more tests for Azure Repository client selection
One test we forgot in #14843 and #13779 is the default client selection.

Most of the time, users won't define explicitly which client they want to use because they are providing only one connection to Azure storage:

```yml
cloud:
    azure:
        storage:
            my_account:
                account: your_azure_storage_account
                key: your_azure_storage_key
```

Then using the default client like this:

```sh
# This one will use the default account (my_account1)
curl -XPUT localhost:9200/_snapshot/my_backup1?pretty -d '{
  "type": "azure"
}'
```

This commit adds tests to check that the right client is still selected when no client is explicitly set when creating the snapshot.
